Claims16
A method of fabricating a nozzle comprising the steps of:
- forming a first microstructured pattern in a first material, the first microstructured pattern comprising a plurality of discrete microstructures;
- deforming at least one of the plurality of discrete microstructures, resulting in at least one deformed discrete microstructure;
- replicating the first microstructured pattern in a second material different than the first material to make a replicated structure;
- processing the replicated structure into a nozzle having a plurality of through-holes in the second material and corresponding to the plurality of microstructures in the first microstructured pattern, said processing comprising removing the first material from the replicated structure.
